Title: Method of making crystalline sugar and products resulting therefrom
Inventor: FUISZ RICHARD C
IPC: A23L27/00
Filed: 1994-09-12
Abstract: ABSTRACT      The present invention is a new crystalline sugar product and method of making same which includes forming a bi-dimensionally stabilized sugar crystalline frame from an outer portion of an amorphous shearform sugar mass, and, subsequently, converting the remaining portion of the mass to a substantially completely crystalline structure which retains the cross-sectional dimension of the sugar crystalline frame.  The present invention also includes co-crystallizing an additive, especially a bio-affecting additive, during the process to provide a co-crystallized product.  The structure of the crystallized product can also be loaded with a non-solvent liquid by force of capillary action in the space created within the structure during the conversion from amorphous mass to crystalline structure.

Title: Wheel-retainer and cross-bar-pivot for tow-trucks
Inventor: BUBIK LESLIE SR
IPC: B60P3/12
Filed: 1994-10-05
Abstract: 1. My "Lifting by the wheel" invention in 1975 started a trend in the towing industry to tow ve-hicles lifted and held by its wheels. A second invention of mine was a big improvement on the previous one which is shown on the attached 3 pa-ges of the patent. N° 4,637,623.   2. This new invention is a further improvement of the wheel-retainer and the Cross-bar pivot see patent N° 4,637,623 - Fig. 1-2-6-7.          There are various wheel retainers on the market now, but the most successful one is still my above mentined design, however I have fond solutions and different ways and came up with a better so-lution.            A second part of this invention is the cross-bar pivot. The requirements are such that it is not easy to design a good one which fulfills all the requirements, mainly because within a restricted hight there is a substantial moment to be counter-acted. Here again my previous design shown in pa-tent N° 4,637,623 is the most successful one  pre-sently on the market. My new inventin is a new approach to this problem improving considerably the previous design. It cost less to make, it is lighter an has better, replacable bearings.     3.  I have found a solution whereby the wheel-re-tainer can be split in two, without  loosing  its necessary freedom of movement to get around  curb problems and get easily into tight weelwells  and then down into towing position. With the previous designs the operator  has  to  handle  the  whole wheel-retainer weldment and has to place it  into a specially shaped socket which alows the  neces-sary movements.          In this invention the arm is permanently attached to the crossbar by a pivot arrangement which  al-los the necessary  free  movements  of  the  arm, which also has a telescoping part for the  neces-sary tire size adjustment. This way the  operator has to handle only one fourth of the weight,  the curved blade which engages the rear  end  of  the wheel  Previously the wheel-retainer  had  to  be stored in or on the truck. With this  new  design the arm can be turned into a  convenient  storing position on the cross-bar.   4.  In drawings which illustrate  embodyments  of the invention Fig. 1 is an elevation, Fig. 2 is a top view of this imbodyment, Fig.  3  is  an  end view.
Patent CA-2134254-A1 (CA)
Inventor: REEDER ROBERT D
IPC: H04M15/00
Filed: 1994-10-25
Abstract: An adjunct processor (16) sends an end-of-address indication, such as a pound sign, along with the address, such as an extension number, to which a call is to be transferred, to a switching system (12, 14). The sent end-of-address indication causes the switching system to not accept further addressing information from the caller (10), thus preventing the caller from modifying the sent address and effecting the transfer of the call to an address different from the sent address, such as a long-distance telephone number. Perpetration of adjunct-assisted toll fraud is prevented thereby.

Filed: 1995-06-15
Abstract: The invention relates to an improvement to a process for manufacturing a closing device constituted by a tapped closing device and a tamper-proof ring comprising, on the one hand, an annular joining strip with controlled deformation and, on the other hand, an inner annular projection. According to the invention, a preforming of the tamper-proof ring is effected:     - by axially introducing in said device a cylindrical mandrel which is provided with an annular peripheral cam such that the lower face of the inner annular projec-tion comes into abutment against said cam, then - by exerting on said device and/or on the mandrel a bearing effort whose force is sufficient to ensure a relative stroke of the mandrel in the device in contact with the cam up to a preforming position maintained for a determined time so as jointly to produce an outward bending of the strip with controlled deformation and a remanent deflection towards the closing device of the inner annular projection so that its upper face remains inclined by an angle with respect to the normal to the axis of the device.

Abstract: Techniques for reducing the amount of junk e-mail received by a user of an e-mail system. A recipient description containing non-address information is added to an e-mail message. The user has an e-mail filter which has access to information which provides a model of the user. The e-mail filter uses the non-address information and the model information to determine whether the e-mail message should be providedto the user. The e-mail filter further has access to information which provides models of the user's correspondents. If the filter does not provide the message to the user, it uses the non-address information and the model information of the user's correspondents to determine who the message might be forwarded to. A sender of e-mail can also use the model information of the sender's correspondents together with the non-address information to determine who the message should be sent to.The techniques are used in a system for locating exp ertise.
